About Course

Laser fundamentals and applications. A Laser is a device that emits light within a process of optical amplification based on the stimulated emission of electromagnetic radiation. Because of its extremely high degree of monochromaticity, coherence, directionality, polarization, and power, etc.,

laser radiation or light has been widely used in high-resolution spectroscopy and imaging, chemistry, optical communications, biomedicine, defense industries, etc.

This course is intended for students who need to understand the basic principles of how lasers work and their main properties. This course provides the scholars a thoroughgoing knowledge of the fundamentals of lasers: their unique properties, their operations, and their applications.

It will equip the students with information on how a coherent light is generated and amplified, the techniques after different lasers design, and applications of laser in spectroscopy, chemistry, medicine, biology, military, and other areas.
